my problem is that my motor bike top speed was 21 mph for the first 1 1/2 to 2 tanks of gas my gas mixture was 16:1 my bike is 2 stroke the i tried 12:1 and thats when i noticed that my max speed would be 18 mph and then it would go up and down and it would be bogging down my speed would go from 18 to 17 to 16 so pretty much it would go up and down it would seam that i would go fasted then slow down a lot so that was just horrible so i got rid of that gas then i tried 32:1 and it just seamed ok the first 2 mins of riding but then it seamed like it just wanted to die out so the i tried tuning out the carb with the brass screw and that seamed like it helped a little but then when i would pull the clutch in it would be fine and then i would noticed that when i would give it gas with the throttle then stop and then it would start to rev up the i would pull the clutch in and then it would rev up so bad that i had to press the kill switch to kill the bike but it rev so bad that it loosened up my carb screw and made it fall off i lost it no big deal i can just go to ace hardware and get it and does it have to do something with my carb i also wanted to buy a new carb and i wanted to know whats the best one out there to buy and whats the difference between them any suggestions
